Since Germany is now minting a "commemorative" coin for a different state each year and the share of those commems from all coins is very big, I would just say that's a normal German coin, not that much a commem in the traditional sense of the word. In 2006 the coins were displaying Schleswig-Holstein and its Holstentor gate. Now they are minting coins for Mecklenburg-Vorpommern and in 2008 some other state. Wikipedia knows more about this.

Yesterday I got my first 2007 coin in downtown Athens. It was a Belgian 2 cent coin, which I received as change for a book. As noted before, I have seen a Slovenian €1 coin, but not in my hands. No Treaty of Rome €2 coins have come to my attention so far, although I have heard of people encountering them on circulation. Of course they hoarded them afterwards!
